| 目的 研究密封组合形式对结构密封性能的影响。方法 开展密封性能试验，从密封形式、装配形式和涂覆形式的3种组合形式开展试验研究，找出结构密封性能影响因素，筛选密封最优组合形式。结果 结构密封3种组成形式分别为有无贴合面的密封形式，干涉装配、湿装配形式，部分涂覆、全涂覆形式。开展2种应力水平下8种密封组合形式的密封性能试验，在保证密封工艺质量条件下，按照飞机结构和受载特点选取合理密封组合形式能有效提高结构密封性能。结论 在飞机应力较高、不常拆的密封部位应选择贴合面密封、干涉装配、部分涂覆的密封组合形式，在飞机结构设计要求间隙装配、常拆卸的密封部位选择贴合面密封、湿装配、部分涂覆的密封组合形式。 |

| Objective To study effect of seal combination on structural seal performance. Method Sealing performance test was carried out to have experimental study from three combinations of the seal form, assembly form and coating form, to find out the influencing factors of structural sealing performance and the optimal combination of screening seals. Results Three forms of structural seals are sealed form: with or without face seal, assembly form interferential assembly, wet assembly, coating forms of partially coated and fully coated. Test of sealing performance of 8 seal combinations under two stress levels were carried out. Under ensuring the sealing process quality, selecting correct sealing combination according to the structure and loading characteristics of the aircraft could effectively improve the structural sealing performance. Conclusion In case of high stress and infrequently disassembled parts of the aircraft, the sealing combination, interferential assembly and partially coated sealing combination should be selected. In the aircraft structure design requiring gap assembly, fit surface seal, wet assembly, and partially coated seal combination is selected for often disassembled seal parts. |
